Its all about preference. AT&T may not be the cheapest but for me it was the fact that Sprint's customer service sucked (was a Sprint customer for 10 years). Verizon was to pricey and had choppy coverage in my area (tested service for 3 days before returning), and T-Mobile coverage was just plain horrible almost nonexistent (also tested for 3 days before returning).
I have to say, no ones prices or coverage (in my area) was better then Sprint, but after they pissed me off and no one was willing to resolve my issue I left.... AT&T for me has shown that they are liable and have provided me with great customer service. Again like I started this reply, its all about preference....

Traditionally, AT&T/Cingular had the best service across Missouri, though US Cellular did really well in certain parts of the state, too. Verizon and Sprint were the worst so far as coverage goes, and that remains true to this day.

That said, I live in Iowa now, and Verizon has the best coverage, with AT&T struggling to keep up. I still have AT&T, though, because of the wealth of rollover minutes I've accumulated over the years.

So yeah, it all comes down to preference. Verizon is not king in all markets, despite what you may have heard.

I left Sprint for AT&T for the iPhone 4 years ago. Even with the iPhones my Family plan was cheaper than any other cell company in my area. After Apple said the iPhone 3G would not receive the full benefits of iOS4 and grew tired of Apple restrictions, I moved to Android (much happier by the way!).

I stayed with AT&T because I got to keep my same monthly plan AND my Unlimited data plan. The biggest reason, AT&T is what works in my area. Not Verizon. Definitely not T-Mobile. Sprint was pretty good service, just not good customer service when you have billing issues.

My phone has been rooted, running a custom image, so sideloading wasn't an issue. But who care that they are just now allowing it. the point is...AT&T finally listen to it's users and are allowing for things like sideloading to happen.

Ditto on the service in DFW or all of Texas for that matter. I have a personal Captivate and a company Verizon BB and ATT wins hands down for coverage, speed and quality in Texas. Which is really all that matters!

ATT could not stop the android craze...They were so one sided with the iPhone it just didn't matter. And now rumor has iPhone 4g wont be out till late fall giving the Android market more room to prosper during this summer.

Why only their "future" phones starting with the Samsung Infuse? Is there some reason they have to hold onto such stupid practices with their already-released phones? Or is that just an admission that they will never update any other phones???

It can only work on Android 2.2 or higher so they are updating the Captivate, Inspire and Aria this week. They are having technical issues with the Atrix but that is next. All phones from now on will have it

I didn't know. I checked for a new update and it said your current software is up to date and then it prompted me that I wouldn't be able to check again for 24 hours. After an hour I went into my Ápplications folder and the option was just there

I manually checked for updates yesterday, said my phone was up to date. Was checking my running apps on my phone and noticed the setting for unknown sources was there :D Must have updated on its own..Inspire 4G in NC!
